TEPEOVED EEE BOTTOM.

To ALL' WHOM TT MAY ooNoERN:.

Beit known that l', DAVID MANUEL, of Boston, in the county of Sulfolh, and' State of Mnssnclhusettshuve invented e. new nud-useful improvement in `Spling-lleds; and I do hereby declare that the followingis a. full, clear, and exact description thereof, which will ennble others skilled in the nrt to molte und use the seme, reference being hnd'to the accompanying' drawings, forming part of this specification, in whichi Figure-1 is n longitudinal vertical section of the-spring bed, showing my improved Form and arrangement o" the springs for suspending the slats.

Figure 2 is u. top view ot' a. bed with my improved springs.

Figure 3 ,is n detached View on the under side of the slet;

Similer letters of rei'erenee indica-to like parts.

'lhis invention relates toimprovements in the constrnetion'and arrangement of a spring bed, sind consists in o new mode of formirnr the s rines and connectirm them to the slots and bedste-Ed whiehseeures an eas alnd a p o o J y gentle plinbility and elnstie power in the springs. v

A represents abedsteod, and B the slats, made in the usual wil-y, running lengthwise. v The slats are suspended on springs, which are formed by ceiling the two ends of n piece of metal wire spirally, and bending-the middle part of the wire into. tworlongcurved sides. The spiral coils a a ere fastened to the head andfoot-erossframe of the bedstea'd by inserting the points of the wire, which are mode toproject from the coils into holes inthe wood, :unl they are licld in place in line with each other by bords, bl), which pass through .the coils et' Ithe springs from one side o f the bedstead to the other7 as shown clearly in figs. 1 and 2. The curved sides r: c, which extend from the inner sides ofthe coils a @,flie below the level of the slats B, and on each .side thereof, at cach end. of n slot. Onthe lower side of the slats B, some' distance from each end, are fastened holders or hooks, d d, opening town-rds the ends, for receiving the middle or cross-connecting'upart of the 'springs between the long curved sides c e in such manner that the slztts are held andsupported in :L level position,'ns shown clearly-in the drawings. By this construction' oi the springs, with two coils', a e, at the ends, andllong curved sides, ce, their action is compound, the curved sides first receiving the pressure, and gently yielding to it without any sudden orjerking movement before the' coils'a a are affected, but which come in ploy and support the slots :Liter they pass their centre. The reaction of the springs when the pressure on them is removed is equally misy and pleasant, i

Having described my invention, I claim es new, Vand desire to secure by Letters Potent- The arrangement of the compound wir@ springs, having spiral ends, a a, attached to the frame of the bed-' stond A, and held by the cords b b; and having also long curvedsides, c c, eonnectediwith the slats B bythe hooked, former., combined, and operating substantially :is and for the purposes herein described.
